What is a Wound Rotor Motor and How Does it Work?

In wound rotor motors, the rotor is "wound" with wire similar to the stator, with their terminal ends connected to 3 slip rings on the output shaft. These slip rings are attached to brushes and variable power resistor banks, where operators can change the speed of the motor by varying the resistance through the rotor …
